Used for 1st time in on a 1,600km ride over 3 days.All weather conditions experienced from 26deg C to 2deg C and raining.Very comfortable, water proof and fit is snug and comfortable.Feet were dry so yes they are waterproof and they are warm in cold temperatures. Feet didn't get too hot on the warmer days either so good all round boot.

Because of the 1 peice design (that keeps them water proof) they are difficult to get into and out of but that will get better with time I think.
